Why do you travel faster on bicycle - or roller

I tested this on 5 people over the last week.
And received the expected response:
* "Efificiency, wheels are more efficient than your legs."
* "Yes, but can you flesh out this efficiency thing?
Why, how, wherefore?"
Blank out.


Try it on your friends and health care practitioners.
fun fun fun!


For bicycle efficiency, your weight is supported by the seat,
so all the energy of your legs goes into torque to create
forward motion. Add toe clips, and you can add energy
in return stroke. *Gearing allows energy use to be coupled
at the most comfortable/efficient rate...


Beautiful, man, your check is in the mail -
